This command sets the queue mode to strict priority or Weighted 
Round-Robin (WRR) for the class of service (CoS) priority queues. Use the 
no form to restore the default value.

• strict - Services the egress queues in sequential order, transmitting 

all traffic in the higher priority queues before servicing lower 
priority queues.

• wrr - Weighted Round-Robin shares bandwidth at the egress ports 

by using scheduling weights 1, 2, 4, 6 for queues 0 - 3 respectively. 

Weighted Round Robin

Global Configuration

You can set the switch to service the queues based on a strict rule that 
requires all traffic in a higher priority queue to be processed before 
lower priority queues are serviced, or use Weighted Round-Robin 
(WRR) queuing that specifies a relative weight of each queue. WRR 
uses a predefined relative weight for each queue that determines the 
percentage of service time the switch services each queue before 
moving on to the next queue. This prevents the head-of-line blocking 
that can occur with strict priority queuing.
